Eye to Eye

Just another quiz about an interesting aspect of the human body you’ll probably enjoy.
The eye is a sense organ for vision. Our eyes are remarkable organs which aid us to put our surrounding environment in perspective. After you eyeball this quiz, let's see how much you remember about eyes.

Thanks for the very nice quiz! I was wondering why you say that cones respond to color. Don't cones also respond to light just as rods do? True they are the photoreceptors that allow for color vision, but they too respond to light, as far as I know...
Thanks again!
